CHAIR-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 740,022, dated September 29, 1903.

Application filed June 17, 1903.

To aZZ whom it may concern.-

Be it known that I, WILLIAM JOHN KELLY, a citizen of the United States, residing at Clinton, in the county of Clinton and State of Iowa, have invented new and useful Improvements in Chair-Bottoms, of whichthe following is a specification.

This invention relates to chair-seats;

The object of the invention is in a ready, simple, thoroughly practical, and positive manner and without the employment of glue orother adhesive or of supplemental fastening devices to secure a chair-seat cover to its base or backing and at the same operation to provide openings for the passage of the fastening devices employed for attaching the seat to the chair frame; furthermore, to eliminate the objectionable features attending the employment of wooden backings heretofore employed, such as cracking and splintering and consequent danger of puncturing the seat-cover, and also those attending the use of metallic backings, such as the necessity of provision of bolts carried by the backing to efiect its attachment to the chair-frame.

With the above and other objects in View, as will appear as the nature of the invention is better understood, the same consists, generally stated, in a metallic backing for chair seats provided with integral cover-attaching means and with openings formed by the provision of such means to permit passage of the fastening devices employed for securing-the chair-seat to the chair-seat frame.

The invention consists, further, in a chairseat comprising a metallic backing provided with integral pins or prongs struck out from the backing and a cover held assembled with the backing by bending said prongs against the cover, the openings in the backing formed by striking out the prongs and presenting passages through which the. fastening devices are passed that hold the chair-seat in position upon the seat-frame.

The invention consists, still further, in the novel construction and combination of parts of a chair-seat, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate correspond- Serial No. 161,944. (No model.)

ing parts, there is illustrated one form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof, and in these drawings Figure 1 is a view of the metallic backing. Fig. 2. is a longitudinal sectional view taken through the backing and attached cover. Fig. 3 is asection-al view exhibiting the chairseat positioned upon a chair-seat frame.

Whilethe chair-seat is herein shown as approximately trapezoidal in contour, it is to be understood that the invention is not to be limited to this particular configuration, as any shape suited to the purpose for which the device is designed may be adopted as may be found necessary or desirable. It is further to be understood that this chair-seat is adaptwith is a series of prongs or pins 2, in this instance shown as triangular, although,if preferred, they may be of other shapes, said elements constituting the cover-attaching means and are formed by striking out the metal by any suitable means for the purpose, the openings 3 formed in the backing by the removal of the prongs constituting openings through which the seat-attaching devices 4 are passed, which devices may be ordinary headed tacks, as shown, or other suitable form of attaching device.

In order to provide the openings S'for'the purpose stated and also to effect a positive and certain assemblage of the seat-cover 5 with the backing, the apices of the prongs are disposed toward the perimeter of the backing, and when the cover is secured in position the prongs are bent backward -that is to say, away from the perimeter-thereby presenting the openings 3. By thus bending the prongs the cover is caused to be positively clamped in position against possibility of accidental separation, and when the fastening devices 4 are driven into the chair-seat frame 6 the cover is additionally held in position. The seat-cover 5 may be of any suitable material, such as leather or fabric, and between it and the backing is interposed a suitable filling, such as hair or the like.

By the employment of a sheet-metal backing, such as described, a strong, light, and durable seat-support is provided which will be practically indestructible and will be free from the objectionable features of an ordinary wooden backing, which is liable to crack and splinter, with attendantdanger of puncturing the cover. Furthermore, by the provision of the openings 3 for the seat-attaching nails puncturing of the backing is obviated and the employment of bolts secured to the backing, such as are in common use, is entirely obviated. At the time that the cover is applied to the backing holes may be punched through the cover, thus to facilitate the ready securing of the chair-seat to the chair-seat frame, these openings being indicated at 7in Fig. 3.

Having thus described the invention, what I claim is- 1. A chair-seat, com prisin ga metallic backing provided with integral pins or prongs in a direction away from the openings, the I openings in the backing, formed by striking out the prongs, permitting passage through the backing of fastening devices for holding the chair-seatin position upon the seat-frame.

2. A chair-seat, comprising a metallic backing provided with integral pins or prongs struck out from the backing thus forming openings in the backing, and the cover held assembled with the backing by bending said prongs backward and down upon the cover in a direction away from the openings, the openings in the backing, formed by striking out the prongs, permitting passage through the backing of fastening devices for holding the chair-seat in position upon the seat-frame, the cover being provided with openings to register with those in the backing formed by the metal separated to produce prongs.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

XVILLIAM JOHN KELLY.
